A combination of favorites: compact weather-shedding Nano Puff insulation to protect and warm crucial areas, and high-loft R2 fleece everywhere else. We revised this hybrid by remapping the PrimaLoft ONE synthetic insulation (60-g, with a recycled polyester shell) to cover the front and back torso and the tops of the arms, from shoulders to cuffs, for concentrated warmth; meanwhile, compressible and stretchy R2 fleece insulation covers the sides, lower torso and underside of arms and breathes without restriction, enabling high reaches on cold-weather rock walls and unrestricted pole plants on frigid ski approaches. Other improvements include a soft, wicking interior storm flap and zipper garage at the chin for next-to-skin comfort, stronger elasticized cuffs and hem for a better seal, and a higher collar with brushed tricot on the inner neck and chin. The two zippered handwarmer pockets ride high (harness and pack compatible) and the full-length, reverse-coil front zipper is backed with a low-bulk wind flap and treated with a Deluge DWR (durable water repellent) finish.
